Abstract
A character identifying device generates a core bit matrix and a mask bit matrix for each reference character pattern scanned by a television camera or like device. The two matrices represent binary coded representation of a reference character pattern at two different threshold levels. An enlarged matrix representation and a contracted matrix representation of the same unknown character pattern are compared to the core bit matrix and the mask bit matrix, respectively, of each reference character pattern and corresponding correlation output signals are generated to unable the identification of the reference character pattern most closely correlated to the unknown character pattern.
